表示制御デバイス、表示装置、表示デバイスの制御方法、表示制御プロ グラム、および該プログラムを記録した記録媒体  DISPLAY CONTROL DEVICE, DISPLAY DEVICE, DISPLAY DEVICE CONTROL METHOD, DISPLAY CONTROL PROGRAM, AND RECORDING MEDIUM CONTAINING THE PROGRAM
技術分野  Technical field
[0001] 本発明は、視野角が変更可能である表示デバイスの表示を制御する表示制御デ バイス、表示装置、表示デバイスの制御方法、表示制御プログラム、および該プログ ラムを記録した記録媒体に関するものである。  The present invention relates to a display control device that controls display of a display device whose viewing angle can be changed, a display device, a display device control method, a display control program, and a recording medium on which the program is recorded. It is.
背景技術  Background art
[0002] 従来から、携帯電話機、 PDA (Personal Digital Assistant)などの携帯機器のデイス プレイとして液晶ディスプレイ（LCD)が広く利用されている。 LCDは、 CRT (Cathode Ray Tube)、プラズマディスプレイなどに比べて、視野角が狭いことが欠点とされてき た力 近時の LCD技術の進歩により、視野角の広角化が進められている。  Conventionally, liquid crystal displays (LCDs) have been widely used as displays for portable devices such as mobile phones and PDAs (Personal Digital Assistants). Compared to CRT (Cathode Ray Tube) and plasma displays, LCDs have been considered to have a narrow viewing angle. Due to recent advances in LCD technology, the viewing angle has been widened.
[0003] し力しながら、上記携帯機器は、電車やバスの車内などにおいて混雑した状況で 利用すると、上記携帯機器の表示画面に表示された内容が周囲の人に覼き見される 虞がある。特に、電子メールの作成および閲覧を行う場合には、その内容が周囲の 人に覼き見されることはプライバシー上好ましくない。  [0003] However, if the portable device is used in a crowded situation such as in a train or bus, the content displayed on the display screen of the portable device may be seen by surrounding people. is there. In particular, when creating and viewing e-mails, it is not desirable for privacy to see the contents of the e-mails.
[0004] この問題に対応して、視野角を制御できる LCDが提案されている（例えば、特許文 献 1〜4参照)。このような LCDでは、通常の広視野角モードと、視野角の狭い狭視 野角モードとの何れか一方力も他方に切り替え可能となっている。なお、狭視野角モ ードとは、ユーザのいる表示画面真正面からは通常どおりの表示画像が視認でき、 斜め方向からは無地画像または別の画像が見えるモードである。  [0004] In response to this problem, LCDs that can control the viewing angle have been proposed (see, for example, Patent Documents 1 to 4). In such LCDs, either the normal wide viewing angle mode or the narrow viewing angle mode with a narrow viewing angle can be switched to the other. Note that the narrow viewing angle mode is a mode in which a normal display image can be viewed from directly in front of the display screen where the user is present, and a plain image or another image can be viewed from an oblique direction.
[0005] 例えば、特許文献 1 (日本国公開特許公報「特開平 9— 105958号公報 (公開日： 1 997年 4月 22日）」）に記載の視野角可変素子は、一対の基板の間の液晶層が、基 板に対して垂直方向に液晶分子が配向することで狭視野角となり、平行方向に配向 することで広視野角となっている。また、特許文献 2 (日本国公開特許公報「特開 200 4— 62094号公報 (公開日：2004年 2月 26日）」）に記載の携帯端末装置は、 2枚の ガラス板の間の液晶の配向を変更することにより、情報表示手段の視野角を変更し ている。 [0005] For example, the viewing angle variable element described in Patent Document 1 (Japanese Published Patent Publication "JP-A-9-105958 (published date: April 22, 997)") is provided between a pair of substrates. The liquid crystal layer has a narrow viewing angle by aligning liquid crystal molecules in a direction perpendicular to the substrate, and a wide viewing angle by aligning in a parallel direction. In addition, the portable terminal device described in Patent Document 2 (Japanese Published Patent Publication “JP-A-2004-62094 (Publication Date: Feb. 26, 2004)”) is a liquid crystal alignment between two glass plates. By changing the viewing angle of the information display means. ing.
[0006] さらに、表示装置をいくつかの区画に分け、それぞれの区画で液晶配向方向等を 異ならせることで、狭視野角モードにおいて、正面以外の方向から表示画面を見た 場合に、表示画面に表示されたものとは異なる別の画像が視認できるようにする構成 のものもある。例えば、特許文献 3 (日本国公開特許公報「特開 2001— 264768号 公報 (公開日：2001年 9月 26日）」）には、液晶層を挟む配向膜が複数の領域に区 画され、隣接する前記領域の配向方向が異なる液晶表示装置が記載されている。ま た、特許文献 4 (日本国公開特許公報「特開 2004— 38035号公報 (公開日：2004 年 2月 5日）」）には、視角方向が異なる第 1の液晶セルと第 2の液晶セルとを交互に 配する液晶表示装置が記載されて 、る。  [0006] Furthermore, by dividing the display device into several sections and changing the liquid crystal alignment direction and the like in each section, the display screen is displayed when the display screen is viewed from a direction other than the front in the narrow viewing angle mode. There is also a configuration that makes it possible to view another image different from the one displayed on the screen. For example, in Patent Document 3 (Japanese Published Patent Publication “JP 2001-264768 A (published date: September 26, 2001)”), an alignment film sandwiching a liquid crystal layer is divided into a plurality of regions. A liquid crystal display device in which the alignment directions of the adjacent regions are different is described. Patent Document 4 (Japanese Published Patent Publication “JP 2004-38035 A (published date: February 5, 2004)”) describes a first liquid crystal cell and a second liquid crystal having different viewing angles. A liquid crystal display device in which cells are alternately arranged is described.
[0007] さらに、特許文献 2に記載の携帯端末装置は、実行中のアプリケーションの種類に 応じて視野角を制御している。これにより、使用状況に応じて自動的に視野角を変更 することができる。  [0007] Furthermore, the mobile terminal device described in Patent Document 2 controls the viewing angle according to the type of application being executed. As a result, the viewing angle can be automatically changed according to the use situation.
[0008] 上述のように、ユーザのいる表示画面真正面では、広視野角モードおよび狭視野 角モードの何れであっても、通常どおりの表示画像が視認されるので、視野角が変 化した力否かを判断することが困難である。このため、ユーザは、本当に視野角が制 御されてプライバシーが守られている力否か不安になる。特に、特許文献 2に記載の 携帯端末装置のように、アプリケーションに応じて視野角が自動的に変化する場合に は、ユーザが主体的に視野角を変更するのではないので、上記不安が増大すること になる。  [0008] As described above, in the front of the display screen where the user is present, a display image as usual is visually recognized in both the wide viewing angle mode and the narrow viewing angle mode. It is difficult to determine whether or not. For this reason, the user is worried about whether the viewing angle is really controlled and privacy is protected. In particular, when the viewing angle automatically changes according to the application as in the mobile terminal device described in Patent Document 2, the anxiety increases because the user does not actively change the viewing angle. Will do.
[0009] また、ユーザが移動するか或いは表示画面を傾けることにより、ユーザが表示画面 を斜めから見れば、視野角の状態を把握できる。し力しながら、この場合、ユーザが 表示画面の斜め方向に位置するので、表示画面真正面に他人が存在する虞があり 、視野角を制御する意味が無くなる。  [0009] Further, when the user moves or tilts the display screen, the viewing angle state can be grasped if the user views the display screen from an oblique direction. However, in this case, since the user is positioned in the diagonal direction of the display screen, there is a possibility that another person exists in front of the display screen, and the meaning of controlling the viewing angle is lost.

Is. In addition, as shown in Fig. 2, etc., it is necessary to display various images on the main screen 4, such as an icon indicating the battery status, an icon indicating the radio wave status, an e-mail text, etc. There is. For this reason, the image display control unit 45 controls the image display unit 50 so as to combine various images using a known superimpose technique and display the combined image on the main screen 4. Thus, in order to display the viewing angle information 60 on the main screen 4, it is not necessary to make the image display unit 50 special.
[0051] なお、現在の視野角の状態は、視野角制御部 42が保持しているから、視野角取得 部 43は、視野角情報を視野角制御部 42からのみ取得してもよい。この場合、視野角 指示取得部 41からの視野角情報の取得を省略することができる。  [0051] Since the current viewing angle state is held by the viewing angle control unit 42, the viewing angle acquisition unit 43 may acquire the viewing angle information only from the viewing angle control unit 42. In this case, the acquisition of viewing angle information from the viewing angle instruction acquisition unit 41 can be omitted.
[0052] 上記構成の携帯電話機 1における処理動作について図 6に基づいて説明する。図 6は、メイン表示部 18が視野角の状態を表示するように制御部 21が制御する処理動 作を示している。  A processing operation in the mobile phone 1 having the above configuration will be described with reference to FIG. FIG. 6 shows the processing operation controlled by the control unit 21 so that the main display unit 18 displays the state of the viewing angle.
[0053] 図 6に示されるように、まず、操作部 16にて視野角変更の操作が行われた力否かを 視野角指示取得部 41が判断する (ステップ S10 (以下「S10」と略称することがある。 他のステップについても同様である。））。視野角変更の操作が行われていない場合 には（S10にて NO)、所定のアプリケーションが実行されている力否かを視野角指示 取得部 41が判断する（Sl l)。  [0053] As shown in FIG. 6, first, the viewing angle instruction acquisition unit 41 determines whether or not the viewing angle change operation has been performed by the operation unit 16 (step S10 (hereinafter abbreviated as "S10"). The same applies to the other steps))). If the viewing angle change operation has not been performed (NO in S10), the viewing angle instruction acquisition unit 41 determines whether or not the predetermined application is being executed (Sl l).
[0054] 視野角変更の操作が行われた場合 (S10にて YES)、或いは、所定のアプリケーシ ヨンが実行されている場合には（S11にて YES)、視野角制御部 42の制御により、視 野角変更部 51が視野角の状態を変更する（S12)。一方、所定のアプリケーションが 実行されていない場合には（S11にて NO)、視野角取得部 43は、視野角制御部 42 力 受信した現在の視野角の状態を参照して、その他の条件により視野角が変更さ れた力否かを判断する（S13)。視野角の状態が変更されていない場合には（S13で NO)、最初のステップ S10に戻って、上記動作を繰り返す。  [0054] When a viewing angle change operation is performed (YES in S10), or when a predetermined application is executed (YES in S11), the viewing angle control unit 42 controls The viewing angle changing unit 51 changes the state of the viewing angle (S12). On the other hand, when the predetermined application is not executed (NO in S11), the viewing angle acquisition unit 43 refers to the current viewing angle state received by the viewing angle control unit 42 and depends on other conditions. It is determined whether or not the viewing angle is changed (S13). If the viewing angle state has not been changed (NO in S13), the process returns to the first step S10 and the above operation is repeated.
[0055] ステップ S 12にて視野角の状態を変更した後、または、ステップ S 13にて視野角が 変更された場合には（S13にて YES)、視野角取得部 43が、変更した視野角の状態 を取得し (S14)、取得した視野角の状態に基づいて、視野角表示制御部 44が、画 像表示部 50における視野角の状態の情報の表示を制御する（S15)。その後、最初 のステップ S 10に戻って、上記動作を繰り返す。 [0055] After changing the viewing angle state in step S12 or when the viewing angle is changed in step S13 (YES in S13), the viewing angle acquisition unit 43 changes the viewing angle. The angle state is acquired (S14), and based on the acquired viewing angle state, the viewing angle display control unit 44 controls the display of the viewing angle state information in the image display unit 50 (S15). Then first Return to step S10 and repeat the above operation.
[0056] 次に、メイン表示部 18に表示される視野角情報 60の例について、図 7〜図 15に基 づいて説明する。図 7〜図 12に関して、分図（a)は広視野角モードでの表示画面を 示しており、分図（b)は狭視野角モードでの表示画面を示している。  [0056] Next, an example of the viewing angle information 60 displayed on the main display unit 18 will be described with reference to Figs. With regard to Figs. 7-12, the partial view (a) shows the display screen in the wide viewing angle mode, and the partial view (b) shows the display screen in the narrow viewing angle mode.
[0057] また、図 7、図 9、および図 11では、視野角情報 60が、「広視野角」および「狭視野 角」の様に文字列で表示され、図 8、図 10、および図 12では、視野角情報 60が、広 い扇形および狭い扇形の様にアイコンで表示されている。このように、視野角情報 60 は、文字列、アイコンなどの各種表示形態で表示することができる。特に、視野角情 報 60は、ユーザが迅速に認識し易!、表示形態で表示することが好ま 、。  In FIG. 7, FIG. 9, and FIG. 11, the viewing angle information 60 is displayed as a character string such as “wide viewing angle” and “narrow viewing angle”, and FIG. 8, FIG. 10, and FIG. In 12, the viewing angle information 60 is displayed as an icon like a wide fan shape and a narrow fan shape. As described above, the viewing angle information 60 can be displayed in various display forms such as a character string and an icon. In particular, it is preferable that the viewing angle information 60 be displayed in a display form because it is easy for the user to recognize quickly.
[0058] また、図 7および図 8では、広視野角モードで広視野角の視野角情報 60wが表示さ れ、狭視野角モードで狭視野角の視野角情報 60ηが表示される。したがって、ユー ザは、表示画面を見るのみで、現在の視野角の状態が広視野角モードであるか狭視 野角モードであるかを容易に判断することができる。  In FIGS. 7 and 8, viewing angle information 60w with a wide viewing angle is displayed in the wide viewing angle mode, and viewing angle information 60η with a narrow viewing angle is displayed in the narrow viewing angle mode. Therefore, the user can easily determine whether the current viewing angle state is the wide viewing angle mode or the narrow viewing angle mode only by looking at the display screen.
[0059] 一方、図 9および図 10では、広視野角モードで視野角情報 60が表示されないが、 狭視野角モードで狭視野角の視野角情報 60ηが表示される。この場合、ユーザは、 表示画面に視野角情報 60が表示されないことにより、現在の視野角の状態が広視 野角モードであることを容易に判断することができる。また、例えば、広視野角モード が通常の視野角モードであり、狭視野角モードが、メール作成時などの特別な視野 角モードである場合、狭視野角モードでのみ視野角情報 60ηを表示すると、ユーザ は、特別な視野角モードであることが判断でき、メール作成などの処理を安心して行 うことができる。  On the other hand, in FIGS. 9 and 10, the viewing angle information 60 is not displayed in the wide viewing angle mode, but the viewing angle information 60η of the narrow viewing angle is displayed in the narrow viewing angle mode. In this case, the user can easily determine that the current viewing angle state is the wide viewing angle mode because the viewing angle information 60 is not displayed on the display screen. Also, for example, when the wide viewing angle mode is the normal viewing angle mode and the narrow viewing angle mode is a special viewing angle mode such as when creating an email, the viewing angle information 60η is displayed only in the narrow viewing angle mode. Therefore, the user can determine that the viewing angle mode is in a special mode, and can perform processing such as e-mail creation with peace of mind.
[0060] 反対に、図 11および図 12では、広視野角モードで広視野角の視野角情報 60wが 表示されるが、狭視野角モードでは視野角情報 60が表示されない。この場合、ユー ザは、表示画面に視野角情報 60が表示されないことにより、現在の視野角の状態が 狭視野角モードであることを容易に判断することができる。また、例えば、広視野角モ ードが通常の視野角モードであり、狭視野角モードが、メール作成時などの特別な視 野角モードである場合、広視野角モードでのみ視野角情報 60wを表示すると、ユー ザは、特別な視野角モードではないことが判断でき、メール作成などの処理を行うと きの警告メッセージとして受け取ることができる。したがって、この場合には、視野角 情報 60wは、点滅したり赤色で表示されたりすることが望ま 、。 In contrast, in FIGS. 11 and 12, the viewing angle information 60w of the wide viewing angle is displayed in the wide viewing angle mode, but the viewing angle information 60 is not displayed in the narrow viewing angle mode. In this case, the user can easily determine that the current viewing angle state is the narrow viewing angle mode because the viewing angle information 60 is not displayed on the display screen. Also, for example, when the wide viewing angle mode is the normal viewing angle mode and the narrow viewing angle mode is a special viewing angle mode such as when composing an email, the viewing angle information 60w is displayed only in the wide viewing angle mode. When displayed, the user can determine that it is not in a special viewing angle mode, and when processing such as creating an email, Can be received as a warning message. Therefore, in this case, it is desirable that the viewing angle information 60w blinks or is displayed in red.
[0061] 図 13 (a) (b)は、視野角情報 60を動画のアイコンで表示した状態を示している。同 図（a)は、扇形が徐々に開くように動画表示されることを示しており、同図（b)は、扇 形が徐々に閉じるように動画表示されることを示している。この場合、狭視野角モード では、同図（a)の左側 2図または同図 (b)の右側 2図が狭視野角の視野角情報 60η として利用され、広視野角モードでは、同図（a)の全 4図または同図（b)の全 4図が広 視野角の視野角情報 60wとして利用される。  FIGS. 13A and 13B show a state in which the viewing angle information 60 is displayed as a moving image icon. The figure (a) shows that the moving picture is displayed so that the fan shape gradually opens, and the figure (b) shows that the moving picture is displayed so that the fan shape gradually closes. In this case, in the narrow viewing angle mode, the left two figures in Fig. (A) or the right two figures in Fig. (B) are used as the viewing angle information 60η of the narrow viewing angle. All four figures in a) or all four figures in figure (b) are used as viewing angle information 60w for a wide viewing angle.
[0062] このように、視野角情報 60を動画で表示することもできる。この場合、静止画で表示 する場合に比べて、ユーザに視野角情報 60を喚起することができる。なお、ユーザ が動画表示に煩わしさを感じる場合に対応するため、操作部 16での操作または表示 設定において、図 13に示されるような動画表示と、図 8に示されるような静止画表示 とが切り替えられることが望ま 、。  [0062] Thus, the viewing angle information 60 can also be displayed as a moving image. In this case, the viewing angle information 60 can be alerted to the user as compared with the case where the still image is displayed. In order to cope with the case where the user feels troublesome in the moving image display, in the operation or display setting on the operation unit 16, the moving image display as shown in FIG. 13 and the still image display as shown in FIG. Desirable to be switched.
[0063] 図 14 (a)〜（c)は、視野角情報 60の例として別のアイコンを示しており、図 8などに 示される扇形のアイコンを上下反対に表示したアイコンを示している。より具体的には 、図 8などに示される扇形のアイコンは、下部が要となり上部が広がった形状となって いる力 図 14 (a)〜（c)に示される扇形のアイコンは、上部が要となり下部が広がった 形状となっている。この場合、ユーザは、メイン画面 4正面から側方へ、どの程度移動 すれば表示画面が見えなくなるかを直感的に判断することができる。  [0063] FIGS. 14A to 14C show another icon as an example of the viewing angle information 60, and shows an icon in which the fan-shaped icon shown in FIG. 8 and the like is displayed upside down. More specifically, the fan-shaped icon shown in FIG. 8 or the like has a shape in which the lower part is necessary and the upper part is widened. The fan-shaped icons shown in FIGS. 14 (a) to (c) It becomes the shape where the lower part spreads. In this case, the user can intuitively determine how much the display screen cannot be seen from the front side of the main screen 4 to the side.
[0064] 図 14 (a)は広視野角モードでのアイコン 60wを示しており、同図（c)は狭視野角モ ードでのアイコン 60ηを示している。また、同図（b)は視野角が広くもなく狭くもない中 位の視野角モードでのアイコン 60を示している。この視野角モードは、ユーザを含む 2 · 3人で表示画面を見る場合に好適である。このように、視野角変更部 51が設定で きる視野角の数に応じて、 3つ以上または連続的な視野角のモードを設けることがで きる。  FIG. 14 (a) shows the icon 60w in the wide viewing angle mode, and FIG. 14 (c) shows the icon 60η in the narrow viewing angle mode. Figure (b) shows the icon 60 in the middle viewing angle mode where the viewing angle is neither wide nor narrow. This viewing angle mode is suitable when a display screen is viewed by 2 or 3 people including the user. Thus, three or more or continuous viewing angle modes can be provided depending on the number of viewing angles that can be set by the viewing angle changing unit 51.
[0065] 図 15 (a) · (b)は、視野角情報 60の例として他のアイコンを示している。図示のアイ コン 60は、 U字形である。同図（a)は広視野角モードでのアイコン 60wを示しており、 同図（b)は狭視野角モードでのアイコン 60ηを示している。広視野角モードのアイコ ン 60wでは、 U字形全体が表示され、狭視野角モードのアイコン 60ηでは、 U字形の 中央部のみが表示される。このように、図 8などで示されるように視野角に応じて扇形 の角度が変化する代わりに、図 15に示されるように視野角に応じて長さが変化する アイコンを利用してもよい。なお、図示の例では U字形のアイコンを利用した力 横長 の長方形のアイコンを利用してもよい。 FIGS. 15A and 15B show other icons as examples of the viewing angle information 60. FIG. The illustrated icon 60 is U-shaped. The figure (a) shows the icon 60w in the wide viewing angle mode, and the figure (b) shows the icon 60η in the narrow viewing angle mode. Wide viewing angle mode icon 60w displays the entire U shape, and the narrow viewing angle mode icon 60η displays only the center of the U shape. In this way, instead of the fan-shaped angle changing according to the viewing angle as shown in FIG. 8 or the like, an icon whose length changes according to the viewing angle as shown in FIG. 15 may be used. . In the example shown in the figure, a horizontally long rectangular icon using a U-shaped icon may be used.
[0066] 以上のように、ユーザが視野角の程度を容易に判断できるものであれば、文字、図 形など任意の記号を利用でき、さらに記号の大きさ、形状、色などを自由に選択する ことができる。 [0066] As described above, if the user can easily determine the degree of the viewing angle, any symbol such as a character or graphic can be used, and the size, shape, color, etc. of the symbol can be freely selected. can do.

[0078] 本発明に係る表示制御デバイスでは、上記視野角情報表示制御手段は、上記視 野角情報が所定の条件である場合に上記視野角情報を表示し、その他の場合に上 記視野角情報を表示しないように表示デバイスを制御してもよい。この場合、ユーザ は、視野角情報が表示されないことにより、視野角情報が所定の条件ではないことを 理解でき、視野角の状態を把握することができる。例えば、上記表示デバイスが、広 V、視野角のモードと狭 、視野角のモードとに変更可能である場合、上記視野角情報 表示制御手段は、一方の視野角のモードである場合に上記視野角情報を表示し、 他方の視野角のモードである場合に上記視野角情報を表示しないように上記表示デ バイスを制御してもよい。  In the display control device according to the present invention, the viewing angle information display control means displays the viewing angle information when the viewing angle information is a predetermined condition, and displays the viewing angle information in other cases. The display device may be controlled so as not to display. In this case, since the viewing angle information is not displayed, the user can understand that the viewing angle information is not a predetermined condition, and can grasp the state of the viewing angle. For example, when the display device can be changed to a wide V, viewing angle mode and a narrow viewing angle mode, the viewing angle information display control means is configured to display the viewing angle when the viewing angle mode is one viewing angle mode. The display device may be controlled so that the angle information is displayed and the viewing angle information is not displayed in the other viewing angle mode.

In the display control device according to the present invention, the viewing angle information display control means may control the display device so as to display the viewing angle information as an icon. In particular, when viewing angle information is displayed as an icon, the viewing angle information is changed by changing the icon display form, such as changing the shape of the icon or changing the color of the icon. It is preferable to express.
[0083] また、視野角が変更可能である表示デバイスと、該表示デバイスの表示を制御する 上記構成の表示制御デバイスとを備える表示装置でも、上述の作用効果を得ること ができる。特に、表示装置が携帯型である場合には効果的である。  [0083] In addition, the above-described effects can be obtained even in a display device including a display device whose viewing angle can be changed and a display control device having the above-described configuration that controls display of the display device. This is particularly effective when the display device is portable.
[0084] 本発明に係る表示デバイスの表示制御方法は、視野角が変更可能である表示デ バイスの表示を制御する表示制御方法であって、上記表示デバイスの視野角に関す る情報である視野角情報を取得する視野角情報取得ステップと、視野角情報を表示 するように表示デバイスを制御する視野角情報表示制御ステップとを含む方法であ つてもよい。  [0084] A display device display control method according to the present invention is a display control method for controlling display of a display device whose view angle is changeable, and is a view field information that is information on the view angle of the display device. The method may include a viewing angle information acquisition step of acquiring angle information and a viewing angle information display control step of controlling the display device so as to display the viewing angle information.
[0085] 上記の方法によると、視野角情報取得ステップにて取得された表示デバイスの視野 角情報が、視野角情報表示制御ステップにて、表示デバイスに表示されるように制御 される。したがって、ユーザは、表示デバイスの表示画面を正面力 見た状態で、視 野角の状態を把握できる。この結果、ユーザは、電子メールの作成'閲覧などのブラ ィパシーに関わる処理を安心して行うことができる。また、視野角の状態を把握する ために、ユーザが移動するか或いは表示画面を傾ける必要がなくなる。  [0085] According to the above method, the viewing angle information of the display device acquired in the viewing angle information acquisition step is controlled to be displayed on the display device in the viewing angle information display control step. Therefore, the user can grasp the state of the viewing angle while viewing the display screen of the display device with frontal power.
